Abstract
The utility model discloses a kind of disc spring devices of the bidirectionally limited structure of band, it includes disc spring cylinder, disc spring bar, disc spring, bolt, nut are characterized in that: having additional swivel nut between disc spring bar and disc spring cylinder, it is machined with ladder platform on disc spring cylinder internal diameter, the distance interval for stretching limit is also reserved between the ladder platform end face and swivel nut end face；The end of disc spring cylinder is provided with threaded hole, the bolt thread is connected on the threaded hole and corrugated expansion joint flange, and nut is screwed on the bolt of corrugated expansion joint flange two sides.The device not only can be carried out bidirectionally limited, but also fitted position problem caused by disc spring thickness deviation also can be adjusted, and enables to meet and bidirectionally limited is precisely controlled requirement.
Description
Technical field
The utility model relates to a kind of mechanical device technical field for balancing line pressure thrust, specifically a kind of bands
The disc spring device of bidirectionally limited structure.
Background technique
Currently, existing disc spring device is made of disc spring bar, disc spring, disc spring cylinder, nut assembly, it is installed on bellows benefit
It repays on device, by the precompression of disc spring, the pressure thrust generated with bellows is cancelled out each other, and reduces the thrust to pipeline support.
But existing structure design can only realize limit when disc spring device compresses, and can not achieve limit when stretching, for having
It cannot be applicable under the application of bidirectionally limited requirement.For how to solve existing disc spring device not can be carried out it is bidirectionally limited
Technical problem is that the application will solve the problems, such as.
Summary of the invention
The purpose of the utility model is to provide a kind of disc spring devices of the bidirectionally limited structure of band.The device not only can be carried out double
It also can be adjusted to limit, and for fitted position problem caused by disc spring thickness deviation, enable to meet two-way limit
Position is precisely controlled requirement.
The used technical solution of the technical issues of the utility model is solved is: a kind of disc spring of the bidirectionally limited structure of band
Device, it includes disc spring cylinder, disc spring bar, disc spring, bolt, nut, it is characterised in that: is added between disc spring bar and disc spring cylinder
There is swivel nut, be machined with ladder platform on disc spring cylinder internal diameter, stretching limit is also reserved between the ladder platform end face and swivel nut end face
Distance interval；The end of disc spring cylinder is provided with threaded hole, the bolt thread is connected to the threaded hole and bellow-type expansion
On device flange, nut is screwed on the bolt of corrugated expansion joint flange two sides.
The technical solution of the utility model further include: the bolt of disc spring cylinder screw thread outer end of hole is provided with a stop nut,
Limitation pressure between the stop nut and the inner screw nut of corrugated expansion joint flange between two corrugated expansion joint flanges
Contracting distance.
The utility model has the beneficial effects that adjustable disc spring device stretch and compress twocouese position dimension,
And consider that rigging error caused by disc spring thickness deviation can be absorbed by swivel nut and the adjustment of end thread hole, it is bidirectionally limited to meet needs
Working condition requirement, and manufacture easy to process.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the vertical section structure schematic diagram of the utility model；
Fig. 2 is partial enlargement structure diagram in Fig. 1.
Main Reference illustrates in figure: 1. bolts, 2. corrugated expansion joint flanges, 3. nuts, 4. disc spring cylinders, 5. swivel nuts, 6.
Disc spring bar, 7. disc springs, 8. compression distances, 9. ladder platforms, 10. distance intervals, 11. screw-in depths, 12. stop nuts.
Below in conjunction with attached drawing by example, the utility model is described in further detail, but following examples are only
The example of the utility model does not represent rights protection scope defined by the utility model, the right of the utility model
Protection scope is subject to claims.
Specific embodiment
As shown in Fig. 1,2,1 in Fig. 1 is bolt, and 2 be corrugated expansion joint flange, and 3 be nut, and 4 be disc spring cylinder, and 6 are
Disc spring bar, 7 be disc spring；Swivel nut 5 is had additional between disc spring bar 6 and disc spring cylinder 4, is machined with ladder platform on 4 internal diameter of disc spring cylinder
9, the distance interval 10 for stretching limit is also reserved between 5 end face of 9 end face of ladder platform and swivel nut；It is set in the end of disc spring cylinder 4
It is equipped with threaded hole, the bolt 1 is threaded on the threaded hole and corrugated expansion joint flange 2, and nut 3 is screwed onto bellows
On the bolt 1 of 2 two sides of compensator flange；The bolt 1 of disc spring cylinder screw thread outer end of hole is provided with a stop nut 12, the limit spiral shell
Limitation compression distance between mother 12 and the inner screw nut of corrugated expansion joint flange 2 between two corrugated expansion joint flanges
8.So when in use, it can adjust the screw-in depth 11 of bolt 2, control disc spring cylinder 4 between two corrugated expansion joint flanges 2
Position, and compression distance 8 is limited, to realize the purpose of this utility model.
